11 Claims. 1

This invention relates to a new and improved automobile boat loading andcarrying attachment.

The principal object of my invention is to provide an attachment of thekind mentioned, working on the principle of an overhead garage door,whereby to enable a single operator unaided to load a boat onto the topof an automobile quickly and easily, and with equal facility to unloadthe same, and without the slightest danger of damage to the boat or tothe car, in either operation.

One of the salient features of the present attachment is the provisionof an elongated main frame adapted to be hingedly attached at one end tothe rear bumper of an automobile, and having pivotally and slidablyconnected thereto a secondary frame that is adapted to be detachablysecured to one end portion of the boat, the main frame having alsopivotally connected to the outer end thereof a prop frame that isadapted to be swung downwardly to a vertical position to prop up therear end of the main frame after one end portion of the boat has beenfastened to the attachment, so that the boat can be swung upwardlyaround the outer end of the main frame as an axis to an uprightforwardly inclined loading position, after which the boat can be raisedwith the main frame and swung forwardly, about the hinging axis of themain frame as a center, over the top of the car in much the same way asone raises an overhead garage door to the overhead position.

Another important feature of the invention is the provision of boatattaching means pivoted on the outer end of the main frame to positively determine the pivotal axis for the boat in the first operation,when the boat is raised oil the ground to the upright forwardly inclinedloading position, during which operation the secondary frame slides onthe main frame to a forward limit position in angular relation to themain frame, shock absorbing springs being preferably provided in themain frame to cushion the abutment of the secondary frame at the forwardlimit of its. movement and accordingly eliminate shock and noise in theoperation of the attachment.

Another feature of the invention is the provision of clips on the mainframe for detachably securing the prop frame in folded relationship tothe main frame when the boat is in transit, whereby to eliminate anylikelihood of rattling.

Still another feature is the provision of a erally,

frame l3.

carrier bar extending transversely on top of the car body, near thefront end, and suitably secured thereto, and carrying suitable means fordetachably securing the forward end portionof the boat thereto when theboat has been slid forward to carrying position, thereby making the boatand its attachment an integral part of the car for transit andeliminating any likelihood of the boat coming loose under wind pressureor shifting rearwardly from a set position.

The invention is illustrated in the accompanying drawings, in which-Figs. 1 and 2 are a top view and side view, re spectively, of a boatloading and carrying attachment made in accordance with my invention; 1

Figs. 3 and 4 are a top view and rear view, respectively, of a carrierbar adapted to be secured to the top of the car for support andfastening of the front end portion of the boat in carrying position;

Fig. 5 is an enlarged sectional detail on the line 55 of Fig. 1, showingone of the two shock absorbing springs provided in the two side membersof the main frame;

Fig. 6 is a side view of the attachment in use, attached to the rearbumper of a car, and showing the parts in full lines in the startingposition, when the main frame and secondary frame are first attached tothe gunwales of the boat, preferably near the stern end, and the partsbeing also shown in dotted lines in the positions assumed when the propframe has been swung downwardly to operative position to prop up therear end of the main frame, so as to enable swinging the boat upwardlyto loading position without danger of scuffing it;

Fig. '7 shows the attachment with the boat in loading position, the topcarrier bar, of Figs. 3 and 4, also appearing in this view in endelevation;

Fig. 8 is a view showing the boat swung for wardly from the position ofFig. '7 to a position resting on the carrier bar, and

Fig. 9 shows the boat moved forward and fastened to the carrier bar incarrying position.

The same reference numerals are applied to corresponding partsthroughout the views.

Referring first to Figs. 1, 2, and 5, the reference numeral Hidesignates the attachment genand it comprises an elongated main frameII, a secondary frame [2, and a prop All of these elements arepreferably of tubular construction for lightness, square aluminum tubingbeing used as far as practicable because of its rust resistingproperties and the ease with which it can be fabricated. The main framecomprises two side members M, which are disposed in spaced substantiallyparallel relation and are rigidly interconnected at one end, as at 15,the cross-member l consisting preferably of two coaxially arranged rods[8 adjustably telescopically connected by a tubular middle piece H, tofit any size boat. Clevises l8 are provided on the side members M at theopposite end of the main frame for hinge connections, as indicated at13', with brackets l9 suitably secured to the rearbumper :20 on theautomobile 2| in connection with which the attachment is used. See Figs.6 to 9. Brackets 22 pivotally mounted on the rods l fi have hooks 23mounted therein, arranged xto'bevapplied to the gunwales of the boat andtightened by means of hand nuts 24 to attach the outer-=e1id'of the mainframe I l securelyito the boat and yet permit zpivotal :movement:"ofithe 'sboat :sabout Gthe across- ;mem'ber I15 :as can: :axis.

The 'tsecorfclar-yv frame 1:2 ."comprises :two side .members25,1which:arerrigidly'iconnected, as Lat -'26tand 21, 'each:ofthese'crossemembers consisting of noaxially disposed rods ;28.zadjustably "telescopically connectedxbyza: tubularimember 29, =to fitany size iboat. :Brac'kets 3B,:tsimilar-to the brackets 22 ,1" are;pivotally mounted i011 the; rods 28 Morass-member 26zandhave-ho'oksz3Iim-ounted therein and zwarranged to be applieduto the gunwalcs of aboat, 'ssimilarlyas .thehooks 23, -andtightenedrby'means. of hand nuts32; so as to securelyconnect therouter .end. of the secondary -frame*l2to the boatpwhile permitting pivotal movement of the secondary frame 2with respect to the-.boatgas will soonsappear.

--a .coiled .compression spring :39 'is also provided inleach .of .theside .members a M adapted .to be compressed between=-the=blocks36-1ands38 when i the secondary tframe 2 reaches the limit position shownin Fig.7, namely, when the boat 40 is :swung pastz an upper deadecenter:position to the forwardly incl-inedposition,- ready for-loadon' top ofthe car. The. springs 39; in. other words, absorb the shock and jar andeliminate ..noise.in.this important, phase of. the. operation of"loading a boat onto the-top .offa-car.

The prop frame 43 comprises two .L-!sl1aped -sidezmembers 4 l the.upperends'of.whiclrarepivotally :connected,- as at' 42, with. the routerends of .the --rods -16, and .-the horizontal-coaxially aligned lowerends 43 of which are telescopically -adgiustablysconnected by a tubularmember 44, vsimilarly as in. the cross-members I 5, 16,- and. .21,to-suit any width: of :boat.

A wooden cross-bar 46 is provided on top of the car, approximately overthe driver's seat, to provide an elevated support for the front endportion of the boat 40 and a place to fasten the boat rigidly andsecurely in its finally loaded position for carrying. SeeFigi-Q. f.Longitudinally extendingslotsll are provided in the opposite ends of thebar 46, and brackets 48 are slidably adjustably mounted in these slotsto permit adjusting dbracketsawrthat carry the suction cups 50 for--r-detachably securing the bar 66 to the top of the car, suchadjustment being necessary because of'th'e difference in transversecurvature of the stops-of .different makes of cars, and it being, of

course, important that the cross-bar 45 be supported-out of contact withthe top of the car, if at all possible. The brackets 49 are pivoted tothebrackets-dt as at 5 l, soas to adapt. the device -to.the.curvature of.the cantop. 'Hooks 52 forconnection to the gunwales of the boat 40 areslidably adjustable theslots '41 and have hand nuts 53 threadeduon .theshanks :thereof, arranged to be tightenedesoias to clamp the-boatto-the'cross-bar it, in the manner. indicated in Fig. 9.

In. operation, the attachment .ofrmyinvention functions :likesa foldableand unfoldable bracket,

speaking-with. reference to the main frame 1 l and secondaryframe.l2,=to which members theboat is directly attached. See Figs. 6 and '7,in whichthe change. imposition of the secondary frame [2. in

relation-tothemain frame H in the unfolding. of

.the bracket isclearly illustrated the side members tofu-the.secondaryframe 12. serving as. radius armsandtby virtue ofttheirslidable pivotal connections with the .side .members of the .main

frame-1 l,.automatically adjusting themselves as atoangularity.withrespectto the main frameas the boats-pivots with-respectto themain frame.

Obviously, in .lieu .of. the combination sliding andpivotalconnectionswith the main frame H, the .secondaryframe I2 .couldbeof telescopic con- .structionandhave only pivotal connections with -.themain frame, so lasto elongate or shorten its length .toaccommodate .thepivotal movement of theboatwith respect to the main frame. How--ever,.the sliding connections with the mainframe afford the advantageof greater simplicity and i economy of construction,.in that fewer partsare used, and-the further advantage that. it. enables incorporating the.shock absorbing- .springs .39-in ,the. main frame, which play such 1animportant :part in sthe operation of this attachment. Referring toFig. 6, whensthe boat 4a is .to .be Lloaded Jonto the.top-.of the carI.2!,..it his 'first ,placed preferably. stern end forwardl'b ehind .the

car, andthe hooks-23are applied tothe gunwales and tightened by means ofhand .nnts.'2 l,-so..-.as topivotally.connect-thestem end of the boat tothe outer end vof the main frame H. "The secondaryframe i2 is.thenslidtoits rearward limit .rposition andthehooks 31 are .likewiseattached .to theggunwales of the .boatand' fastened by tightening thenuts 32 to pivotally connect the boat vto-thee econdary frame 12.Theprop framel3' is then disconnected from the clips 45, so'as to befree to swing downwardly by gravity, and the stern end of the boat israised to allow the prop frame I3 to swing into position under it. asshown in dotted lines in Fig. 6. The boat is now ready for loading, andthe first step in that direction is for the operator to take hold of thebow of the boat and raise it to a substantially vertical position,swinging the boat about the crossmember H5 at the outer end of the mainframe I i as an axis. There is sufficient clearance under the stern, byvirtue of the outer end of the main frame being propped up on the propframe I3, so that there is no danger of the boat getting scuffed, andthe average man or woman, I or an older boy or girl, will have nodifficulty whatever in swinging the boat upwardly while it is sosupported at the stern end, it being obvious that to a certain extentthe weight of the boat is counterbalanced with. respect to the pivotalaxis I5, and, as the boat is raised farther and farther, more and moreof the weight is assumed on this pivotal axis. In this pivotal movementof the boat'relative to the main frame I i, the secondary frame I2slides forwardly on the main frame at graduallyincreasing angularityuntil it reaches the limit position shown in Fig. '7, where the boat isforwardly inclined in the loading position, ready to be'swung forwardlyand upwardly from the. stern end over the top of the car, in much the.same way as one would move an overhead garage door to the overheadposition. When the boat passes the upper dead-center in moving towardthe loading position of Fig. 7, it will, of course, tend to fall towardthe car, but soon after it passes the dead-center the blocks 36encounter the springs 39 and they are compressed slightly as theyassume'the load, thereby avoiding shock and jar as well as noise. Theboat in the loading position, shown in Fig. 7, can easily be raisedfrom.-

the stem end by the same single operator-without any exertion, and afterit has been raised a short distance, the weight of the boat and theattachment is balanced with respect to the hinging axis I 8, so that thefurther movement necessary to get the bow over the bar 46 isaccomplished very easily and the boat does not drop heavily upon thebar, but engages it quite lightly, even if the operator is inexperiencedin the handling of this equipment or does not exercise much care in theloading operation. Fig. 8 shows the boat at the point in the loadingoperation when the boat has just come to rest on the cross-bar 46 andhas not yet been slid forward to the carrying position shown in Fig. 9.In this final forward movement, the secondary frame I2 again slides onthe main frame II to a position of less angularity with respect thereto,and the weight of the stern end of the boat is, therefore, assumedentirely by the main frame Ii. In other words,

the secondary frame !2 cooperates with the main frame H in the supportof the boat until the cross-bar 4E5 assumes support at the bow of theboat, and throughout thisloading operation, the springs 39 arecompressed to varying degrees, depending, obviously, upon the angularityof the boat to. The springs 39, therefore, also play an important partthroughout the actual loading operation in addition to absorbing theshock when the boat is swung past the vertical deadcenter position intothe loading position of Fig. 7. After the boat has been slid forward tothe position of Fig. 9, the hooks 52 on the cross-bar. 46 are attachedto the gunwales and the hand nuts 53 are tightened to clampthe boatfirmly onto the '6 cross-bar, so that the boat is not apt to get looseor shift 'rearwardly from its set position. The prop frame I3 can befastened in the folded position of Fig. 9 by means of the clips 45before or after the boat has been clamped to the cross-bar 45 by meansof the hooks 52. It should be evident from Fig. 9 that there is noobstruction to good visibility forwardly or rearwardly for the driver ofthe car when the boat is loaded on the car with my attachment, and,furthermore, there is nothing to obstruct access to the rear trunkcompartment. In unloading the boat, the procedure described is, ofcourse, repeated in the reverse order. Obviously in'unloading, theoperator should be careful to release the secondary frame I3 from theclips 45, so as to be sure that this frame will be in readiness to reston the groundwhen the boat is moved from the position of Fig. 8 to thatof Fig. '7, otherwise the stem end of the boat would, of course, comeinto contact with the ground. The frame I3 gravitates automatically tothe operative position when released. The springs 39 again absorb shockand jar in this portion of the unloading operation, and, inasmuch as theboat, when disposed in the position of Fig. 7, is so close to adead-center position, the operator has no difliculty in swinging ittoward and past dead-center toward the position of Fig. 6, andthereafter the final steps in the disconnection of the boat from theattachment I0 are believed to be obvious.

It is believed the foregoing description conveys a good understanding ofthe objects and advantages of my invention. The appended claims havebeendrawn to cover all legitimate modifications and adaptations.
